Over the years, Shenzhen Peng Hao Technology Co., Ltd. has been focusing on product research and development. The company spends 5% of its annual sales on the construction of R&D center, the development of new products and the introduction of advanced equipment. R&D Center has introduced a series of advanced instruments to support the research and development of new products, such as:
(1) x-ray diffractometer
X-ray diffractometer uses diffraction principle to determine the polycrystalline phase, and accurately carries out phase analysis (qualitative or quantitative), cell parameter determination, lattice distortion determination, crystallinity determination and Rietveld analysis. This method is simple, flexible and reliable, and is suitable for the analysis of various polycrystalline phases. Our company is mainly used to analyze the phase and crystal structure of battery materials.
(2) Specific surface area analyzer
The specific surface area analyzer is a special equipment for detecting the specific surface area of particulate matter. Specific surface area is the surface area per unit mass (㎡/g), which is one of the most important physical properties of powder materials. Our company is mainly used to test the specific surface area of powder main materials and additives and monitor the quality of powder materials.
(3)X-ray fluorescence spectrometer
X-ray fluorescence spectrometer is an analysis method based on polarized energy dispersion (ED-XRF), which can analyze solid, powder, liquid and other samples. The analysis range is from Be to U. The application range of X-ray fluorescence spectrometer in various industries is expanding, and most analytical elements can be analyzed with it. It has the characteristics of fast analysis speed, wide measurement range, little interference and no damage to samples. Our company is mainly used for the detection of harmful substances in the EU ROHS directive, as well as the rapid analysis of material element composition and coating thickness.
(4) Gas chromatograph
Chromatography (GC) is based on the different partition coefficients of each component between mobile phase and stationary phase. When the sample is carried into the chromatographic column by the carrier gas, it is repeatedly distributed between the two phases. Because of the different dissolution, adsorption, permeation or ion exchange of stationary phase components, the retention capacity is obviously different. After passing through the chromatographic column, the components are separated from each other, flow out of the chromatographic column in turn, enter the detector and display on the recorder. According to the order, peak height or peak area, the components can be distinguished and the content of each component can be calculated. Our company uses GC to detect the gas composition and content in the process of battery charging and discharging.
(5) Laser particle size analyzer
The principle of laser particle size analyzer is that the laser beam meets the particle sample in the sample pool and interacts with it during its propagation, and the converged beam is scattered to the detector and converted into electrical signals for output. It is widely used to test the particle size of various nonmetallic powders and metal powders (such as copper powder, alloy powder and rare earth metal powder), and has the characteristics of good repeatability, wide test range and rapid test. Our company is mainly used to test the granularity and check the quality of powder materials.
(6) X-ray perspective
X-ray perspective can use the penetrating power of X-rays to analyze the internal structure of substances, and is widely used to perspective objects such as bones, nonmetals, thin metals and plastics. Our company is mainly used to observe the internal structure of batteries.
(7) Atomic absorption spectrophotometer
Atomic absorption spectrophotometer atomizes the elements to be measured into ground-state atomic vapor by heating, selectively absorbs the characteristic radiation emitted by hollow cathode lamp, and measures its absorbance. The absorption intensity is directly proportional to the content of detected components in the test solution, and the element content is calculated according to Lambert-Beer law. Mainly used for the analysis of trace elements and impurities, it has two main advantages: high sensitivity and good selectivity. Our company is mainly used for the analysis of trace impurity elements in battery materials and the accurate test of harmful metal elements in ROHS instructions.
(8) Inductively coupled plasma high frequency emission spectrometer
Inductively coupled high frequency plasma emission spectrometry (ICP-OES) analysis is a qualitative and quantitative analysis method, which excites the sample in a plasma light source, makes the elements to be measured emit radiation with characteristic wavelength, and then measures their intensity after splitting. ICP-OES has the advantages of fast analysis speed, high sensitivity, good stability, wide linear range, small matrix interference and simultaneous analysis of multiple elements. It has been widely used in geology, environmental protection, chemical industry, biology, medicine, food, metallurgy, agriculture and other industries. Our company is mainly used to analyze the elemental composition and content of battery materials.
